Abstract:

Background/aims:
Cancer is the most common cause of death worldwide with approximately one third of people being diagnosed with cancer in their lifetime. Pinostilbene hydrate (PSH) A methylated derivative of resveratrol Has been reported to possess antioxidative Cardioprotective and anticancer properties. However the antimetastatic effect of pinostilbene in oral squamous cell carcinoma (OSCC) remains unknown.
Methods:
In this study We investigated the effect of PSH on antimetastatic activity and the relevant signaling pathways underlying mechanisms of SCC-9 SAS and HSC-3 oral cancer cell lines by MTT assay Wound healing Transwell assay Zymography and western blot analysis.
Results:
Our findings indicated that PSH inhibits migration and invasion ability by reducing the protein activity and expression of matrix metalloproteinases-2 (MMP-2) in all three cell lines. Moreover • The phosphorylation of extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinases (p38) had significant inhibitory effects in the presence of PSH in the SCC9 and SAS cell lines. A combination of ERK1/2 and p38 inhibitors with PSH also reduced the migration and activity of MMP-2 in the SCC9 and SAS cell lines.
Conclusion:
This study demonstrated that PSH suppresses MMP-2 enzymatic activity by downregulating the p38/ERK1/2 pathway and that it might be a promising agent for preventing OSCC cell metastasis.
